Sustainability in engineering design
Published in Riadh Habash, Green Engineering, 2017
Green engineering promotes innovative thinking toward sustainability which may not be achieved by applying the newest technology or process. The green engineer must redefine the project to evaluate the full life cycle of the inputs and outputs to achieve sustainability throughout the project. The 12 principles provide a framework to guide engineers into considering suitability through all stages of design. They encourage the redefinition of the task to consider the full life cycle, inputs, and outputs. A number of these principles are already implemented in the water treatment and wastewater treatment industries. The twelve principles aim to allow systematic incorporation of green engineering throughout the entire project to the benefit of the environment and society (Anastas and Zimmerman 2003).
Applications of Chemical Kinetics in Environmental Systems

Green engineering follows a set of core principles laid down in 2003 in what is known as the “Sandestin Declaration,” which are given in Table 4.19. A definition of “Green Engineering” is “Green engineering is the design, commercialization, and use of processes and products that minimize pollution, promote sustainability, and protect human health without sacrificing economic viability and efficiency” (U.S. Environmental Protection Agency, N/A). Closely aligned with the principles of green engineering are two other related concepts: (1) Sustainability defined as “meeting the needs of the current generation without impacting the needs of future generations to meet their own needs” and (2) life cycle assessment (LCA).
Carbon Nanotubes for Greening the Environment
Published in Shrikaant Kulkarni, Iuliana Stoica, A.K. Haghi, Carbon Nanotubes for a Green Environment, 2022
Green engineering is the design, commercialization, and use of processes and products in a manner that reduces pollution, promotes environmental and green sustainability, and minimizes risk to human health and the surrounding environment without sacrificing economic viability and efficiency of the processes and the products.25,26
A bi-level optimization model for technology selection

A bi-level optimization model for leader-follower technology selection problems was developed in this work. The original bi-level, bi-objective MINLP formulation was then reformulated into a more tractable single-level, single-objective MILP model. The model was demonstrated on a case study involving selection of NETs. The results show how economic incentives can be calibrated and imposed by the leader to influence the follower’s final choice of technology, such that the latter aligns with the leader’s preference. This alignment is critical in the successful adoption of appropriate technologies. The problem structure and modeling framework is broadly applicable to many industrial problems that involve leader-follower interactions; for example, it has interesting practical implications for interactions between government and industry, between industry and consumers, or among firms in a supply chain. There are promising green engineering applications for the selection of clean technologies (e.g. energy sources, packaging materials) to address current environmental concerns (e.g. climate change, plastic pollution). The use of this model for consumer choice architecture in green product commercialization is of particular interest. Future work can explore such applications, as well as model extensions that account for parameter uncertainties and temporal aspects.
Temperature rise in workpiece and cutting tool during drilling of titanium aluminide under sustainable environment

Green engineering starts from the design of a product to its commercialization while employing processes and resources that are realistic and cost-effective with minimum generation of harmful by-products that may risk the health of living organisms and ecological imbalances [3]. The ecological, economic, and social impact of the manufacturing process is considered in sustainable manufacturing and they aim to improve technologies for various manufacturing processes with key emphasis on decreasing the use of harmful materials, controlling the generation of waste and emission of greenhouse gases [4,5].
